Answer: 4x+15≥20
Step-by-step explanation:
To find the inequality, we can break down the sentence.
The first part says the sum of a number times 4 and 15. Let's split this apart. We begin with "the sum of". This tells us that we will be adding two things together. The first is a number times 4 and the second is 15. Let's use x for the unknown number. Therefore we would have 4x+15.
The last part is at least 20. This means the sum has to be 20 minimum. So the inequality we use should be greater than or equal to.
Therefore, the inequality is 4x+15≥20.
Answer: y67
Step-by-step explanation:5n − 19 + n + 7 = 144 − 6n
6n − 12 = 144 − 6n
12n = 156
n = 13
m∠z = (144−6n)°
m∠z = (144−6×13)°
m∠z = y67
Answer:
88%
Step-by-step explanation:
The correct answer is 88% because 12% of the pens are defective.
As a result, 12% ÷ 5000 = 12 ÷ 100 x 5000
= 600
There are 600 defective pens.
The pens that are left are 5000 - 600 = 4400.
4400 pens are in good working order.
This means that 88 percent = 4400 ÷ 5000 x 100
